Extracting antimony from high arsenic and gold

2019-6-1  Antimony is a lustrous, silver-white, non-malleable metal with poor electrical and thermal conductivity. At room temperature, antimony cannot be oxidized by humid air or pure water. Metallic antimony is too brittle to be used alone and is always used as an alloy or compound (Anderson, 2012; Zhao, 1987).

Extraction of Antimony

Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated.
